The debris found on the ocean floor off Florida's Atlantic coast is believed to be from the space shuttle Challenger.

A 20-foot section of Challenger's hull was found by divers while searching for downed World War II-era aircraft as part of a History Channel documentary. The filmmakers found a patch of seafloor that was partially covered in sand. The filmmakers contacted NASA because they thought the debris could be related to the space agency.

The debris from Challenger was confirmed by NASA. The discovery of seven astronauts was announced by NASA.

Bill Nelson, administrator of NASA, said in a statement that the tragedy will be remembered by everyone. This discovery gives us an opportunity to pause and reflect on how this tragedy changed us.

NASA will determine the next step in the recovery of the Challenger hull, which was found on the ocean floor. All of the debris is owned by the government.

NASA had been flying the "space trucks" to and from low Earth for almost five years before Challenger's 10th launch. A seal on a solid rocket booster malfunctioned 73 seconds into flight due to freezing temperatures on the night before launch.

Christa would have given lessons from space. The planned six-day mission would have seen astronauts conduct scientific research and release a satellite.

The first in-flight deaths in NASA's manned space program took place in 1961. Pre-launch tests were being conducted on the ground by three astronauts who died in a fire in 1967. Seven people were killed when the space shuttle Columbia broke apart.

Half of Challenger's debris has been recovered by NASA and is on display at the Kennedy Space Center.

The six-part documentary series will include footage from the Challenger find.
